Title: Shutter equipped with anti-break-in members
Inventor: FEVRIER ROBERT LOUIS JULES
IPC: E05B65/00
Filed: 1984-11-21
Abstract: The shutter comprises blades which are articulated to each other in order to be either folded onto one another in two series located on the sides of a picture window, or extended opposite the picture window to close off the latter. It moreover comprises safety means by which each blade is made integral with a fixed case when the shutter is closed, so as to constitute a barrier countering easy breaking-in of the shutter. It is characterised in that the safety means comprise striking plates 25 which are integral with each blade 10, 11 ... and bolts 26, which are integral with the slides mounted so as to be mobile in the fixed guideways perpendicular to the articulations of the blades 10-11. Having closed the shutter, the slides are moved in the direction of the arrow F2 so that each bolt 26 engages into a striking plate 25. Sets of striking plates-bolts are provided at the upper and lower part of the blades so that these will be held in position at the top and at the bottom. The closed shutter is thus made integral with the fixed case and constitutes an efficient barrier against break-ins.
